<H2><A NAME="4_8">4.8 Specifying colors in JpGraph</A></H2>
<P> Colors can be specified in three different ways</P>
<OL>
<LI> By using one of the, roughly, 400 pre-defined color names, e.g<DIV class="phpscript">
<CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">
(</FONT><FONT color="#DD0000">&quot;khaki&quot;</FONT><FONT color="#007700">);</FONT><FONT
color="#0000BB"></FONT></FONT></CODE></DIV>
<P> A named color can also be modified by adding a adjustment factor. An
 adjustment factor, 0 &lt; f &lt; 1, a smaller value will give a darker
 version and a value of 0 or 1 will return the original color. A value &gt;
 1 will make the color brighter. A few examples<DIV class="phpscript"><CODE>
<FONT color="#000000"> <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">
(</FONT><FONT color="#DD0000">&quot;khaki:0.5&quot;</FONT><FONT color="#007700">
);&nbsp;</FONT><FONT color="#FF8000">//&nbsp;A&nbsp;darker&nbsp;version&nbsp;of&nbsp;&quot;khaki&quot;
<BR></FONT><FONT color="#0000BB">SetColor</FONT><FONT color="#007700">(</FONT><FONT
color="#DD0000">&quot;yellow:1.2&quot;</FONT><FONT color="#007700">);&nbsp;</FONT><FONT color="#FF8000">
//&nbsp;A&nbsp;slightly&nbsp;lighter&nbsp;version&nbsp;of&nbsp;&quot;yellow&quot;</FONT><FONT color="#0000BB"></FONT>
</FONT></CODE></DIV></P>
<P></P>
</LI>
<LI> By specifying a RGB triple, e.g.<DIV class="phpscript"><CODE><FONT color="#000000">
 <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">(array(</FONT><FONT
color="#0000BB">65</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">
100</FONT><FONT color="#007700">,</FONT><FONT color="#0000BB">176</FONT><FONT
color="#007700">));</FONT><FONT color="#0000BB"></FONT></FONT></CODE></DIV>
<P></P>
</LI>
<LI> By specifying the color as a hex string value<DIV class="phpscript">
<CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">
(</FONT><FONT color="#DD0000">&quot;#A16BFF&quot;</FONT><FONT color="#007700">);</FONT><FONT
color="#0000BB"></FONT></FONT></CODE></DIV>
